I have a strange situation where some apps will not install on my watch. The apps are listed in the watch app with INSTALL buttons. Some apps install as expected upon tapping INSTALL. However for certain apps, upon tapping INSTALL the spinner appears for a fraction of a second then INSTALL reappears. This is the sign that they won’t install. Upon tapping INSTALL again, it spins indefinitely. Exit to the home screen and reenter the watch app, spinner gone, INSTALL is back. Have restarted both watch and phone, deleted and reinstalled the offending apps from the phone, and unpaired and repaired the watch, no improvement.

This all started when I noticed that some apps were not functioning properly on the watch (the main one was Due, which is one of the only apps I actually want on the watch, and of course is one which will not install). I previously didn’t care and had loads of apps on my watch but the apps on watch did not match the list on the app. I had to manually remove all the apps from on the watch itself from the honeycomb screen. Have not been able to get Due back on to the watch since.

This article covers the symptom but its suggestions have not yielded any solution.
